...they even go the extra mile

-WOW, what a difference

"I hired Tony Vain to serve the father of my kids, a deadbeat dad who refuses to pay child support and who doesn't show up for his custodial time.  Deadbeat Dad easily eluded the first process server for months, forcing a re-issuance of the contempt papers and another hearing... Well, I took a chance on Tony Vain, and WOW, what a difference! Tony is a true professional -- and he accomplished service on Deadbeat Dad in less than a day.  Tony Vain is smart, patient and aggressive... and an excellent communicator... You know he is working on your behalf.   I would definitely recommend Tony Vain Investigations Inc.  Amazing!
